As i know and I heard article sites has a mini site network and the article which we have submitted in it will distributed in their mini site network automatically which means article is syndicates to other article sites or network sites,it is useful from the seo point of view because you have no need to submit article in too many article web sites and also your links will spread on other web sites.
